Yes, 400W is enough as long as your PSU is from a reliable/reputable Tier 1 or Tier 2 brand/model/series.
You can put all your components in here and it will tell you how much wattage you need

Also this is a good thread to explain the differece in quality between the psu's

^Not a good definition of good power supply.
You can disable sleep states in motherboard.
Difference between bronze and gold efficiency is 5% in ideal condition. Will be less in non ideal situation. With a 450w power supply you can even run a 1070 these days.

That´s my definition where nothing could go wrong and will be future proof for upgrading to for example a RX480
I´m aware the sleep states can be switched off, if a future motherboard provides this option in the future
and you will have to do that manually, without knowing, someone could be frustrated
also energy saving is always a good thing
(less heat)
5% are 20W lost energy in this case
50% usage:
bronze 340W usable
gold 360W usable

Surely that's not how it works lol? It is based on how efficiently the power from the wall is used. It does not mean you're getting 85% amount of power from a 500 watts power supply for example.
More watts from the wall going into the power supply compared to what the power supply really needs = watts lost. For example your wall inputs 400 watts into the power supply but only 250 watts is used. That's where the effiency is determined. Or have I been wrong all my life?
